Outline of Final Research Achievements

We studied two examples of noncommutative probability theory. One is the extension, to the unbounded case, of the q-deformed probability theory which was previously studied in the bouded case by the author. The other is the twisted probability theory based on the twisted independence. Here the twisted independence for non-commutative random variables is based on the twisted canonical anti-commutation relations of W. Pusz. Besides these results we proved the no-go theorem for the existence of a notion of independence, to the case of the non-trivial values in the deformation parameter associated with the interacting Fock spaces of one-mode type.

Academic Significance and Societal Importance of the Research Achievements

非可換な世界(物理的には量子論と関係する)においては、通常の確率論の他に、それとはパラレルな関係にある複数の確率論たちが(数学的に)併存していることを、具体例(q変形確率論と捻じれ確率論)を構成することにより示した。特に、捻じれ確率論は、近年量子コンピュータの数学理論で注目を集めてるエニオンという仮想粒子と関係していると考える。純粋数学での成果ではあるが情報化社会の基盤的問題ともリンクしている。
